if you want a good independent Ducati workshop, http://louigimoto.com/ near Bristol otherwise its Baines https://www.silverstonecycle.co.uk/ over at Silverstone.
both know their stuff and have good racing pedigree. I remember going to the original Dick Lovett Ducati in Swindon to get my 851 serviced, they were more interested in trying to sell me a new bike.
Baines, £90 + parts for a full service!!! that's me out of the equation then.
